I originally bought an EP175, but it was not enough sub for a living room environment. I uprgaded to an EP350 and have been impressed with it ever since. To compare an EP175 to other subs would not be a fair comparison. Personally, I'm surprised that Axiom even continues to make the 125 and 175.

Now, concerning the review page, again. When I click on the 3rd and the 7th link for the M80's. It doesn't even direct me to an Axiom speaker, that I can find. Is the review site ready for prime time?

GTP, on at least one point there appears to be a misunderstanding on your part or in sources you may have read and are relying upon: there is no "brickwall type high pass filter". There's a low-pass filter of that type operating to cut off response above 100Hz in some models(e.g., my six year old EP500)and 150Hz in others. "Room gain" occurs in the lowest 20-40Hz octave or slightly higher in very small rooms; the low-pass filter in question has nothing to do with this. Some models do offer the ability to switch in a subsonic filter for frequencies below about 20Hz to prevent subsonic disturbances, such as rumble when playing LPs, from creating a problem.

What really got me upset was that my opinion doesn't matter even though I own and Axiom subwoofer (if you can call it that)M22s, M2s, VP150. Check out my posts on AVS where I battled it out for year recommending Axioms to people (except their subwoofers) Which I still like the M22s and M2s, and still have recently recommended them on AVS.

Find me a thread where Axiom subwoofers have been recommended in the last few years, there isn't one, nobody wants them cause they are so dated compared to the competition and are priced at a premium at that. Looking at measurements of the PB12 NSD and it kills the EP600 under 40hrz. $769 VS $1860. The $400 Emo sealed sub kills the EP400 and does it at 60-70% less. $1100+ for the EP400 with performance like that graph, and its a hollow box ZERO bracing just a 3/4" mdf a 8" woofer and an amp nothing special.

The OP posted asking about subwoofers and actually thought the EP600 and 800 was in the same league as the SubM and Ultra will there not in the same league the EP600 can barely compete with SVS and other brands lower end models. If your going to spend the $2K on an Axiom subwoofer you should know your buying an outdated underperforming, under built subwoofer.

Wheres the measurements? Really that reviewer just gave his opinion just like I gave mine right? So if my opinion doesn't count being an actual owner why does his. Wheres the in room response graph, ect....?
